csvprintf is a simple UNIX command line utility for parsing CSV files.

csvprintf works like the printf(1) command line utility: you supply a
printf(1) format string on the command line, and each row of the CSV file
is split into arguments and formatted accordingly. The format specifiers
in the format string contain numeric or symbolic column accessors to
specify which CSV column to format.

csvprintf can also convert CSV files into XML and JSON documents
and Bash variable assignments suitable for eval(1).
